Application filed January 27, 1969.

To all whom it may concern:

Be it known that I, HUGH D. WALKER, of Grimsby, Lincoln county, Ontario, Canada, have invented certain new and useful Improvements in Steaming Apparatus, of which the following is a specification, hke letters and numerals in the drawings and description designating like parts.

This invention relates to steamlng apparatus, and is of particular utility when embodied in a portable outfit for cooking preserves, such as fruit, or other edibles, near their source, as in an orchard, so that the delay, expense, and injury to such articles, resulting from their transportation, can be avoided. I wish it understood, moreover, that I contemplate the utilization of my mprovements in any field of use for which they are fitted by their nature,

An important object of my lnyention 1s to provide a steam generator, including a boiler, furnace, feed-water reservoir, and other accessories, of simpler and less expensive construction than have been available heretofore for the use of persons having occasional need to consume steam in relatively small quantities, and for whom the use of much apparatus requiring steam, such as soap kettles with steam jackets, has been prevented by the prohibitory expense attending the generation of steam 1n quantities and at a pressure suitable for such applications thereof. One of the most lrnportant requisites in such a portable plant is the boiler, with its furnace, which must be eiiic1- ent, capable of using a wide range of fuel, with little attention when in use, and not subject to rapid deterioration for want of care when out of use, or lack of mechanical skill on the part of the users. Accordingly, in making provision by my invention to accomplish the above objects, I have made use of the domestic boiler or hot water reservolr ordinarily used in connection with kitchen ranges and of very simple interior construc tion, not requiring the cleaning out of tubes, and such a boiler I support in a horizontal position upon a fire box which preferably extends beneath the front portion of the boiler, the latter having a jacket for the remainder of its length, with substantially horizontal baffle-plates which direct the course of the products of combustion backward along the under surface of the boiler, whence they come forward above the bafile- Specification of Letters Patent.

plates and along the upper surface of the boiler, toward the front of the fire box, above which I prefer to provide a smokestack of any suitable construction. In order that the fire box may be constructed of relatively light material such as sheet iron, I prefer to provide upwardly extending fire bars of suitable construction, of which one convenient form may be found in corrugated plates of cast iron extending from the fire grate upward toward the battle-plates.

The various features of my invention will be illustrated and described fully in the accompanying drawing and specification and set forth in the claim.

In the drawing, Figure 1 is a view in perspective of a steaming apparatus in the construction of which my improvements have been embodied, parts being broken away to reveal interior construction; Fig. 2 is a fragmentary horizontal sectional view of a portion of the vertical fire bar, taken on the line Ke -X in Fig. 2.

In the embodiment of my invention selected for illustration and description to enable ready and complete understanding of my improvements, the part designated by the reference numeral 1 is the boiler, which may be considered to conform in essential respects with the wellknown hot water boiler or reservoir usually connected with the waterback of kitchen ranges, so that detailed description of its construction is unnecessary. I prefer to provide it with a glass feed gage 2, and I have shown it as provided with a suitable inlet 3 in its bottom near the middle, and with a steam outlet 4: extending from the top of the boiler.

In accordance with my invention I have shown the boiler as supported in a substantially horizontal position above a fire-box 5 situated beneath the front half of the boiler, the end 6 of the latter being preferably flush with the front wall 7 of the fire-box and deriving its forward support from a circular seat 8 in said wall, while the rear of the boiler is supported in any suitable manner, as for example by portions 9 of the rear wall 10 of the fire-box which has apertures 11 to pass the products of combustion into the jacket 12 surrounding the overucts of combustion and direct them into a horizontal path along the lower half of the boiler throughout its extent,.until they reach the end thereof, when they follow the path indicated by the arrows upward and then forward along the upper half of the boiler and out of the smoke-stack 15, which may be of any suitable 'form and in the instance illustrated is shown as of well- KnoWn construction.

A suitable fire grate 16 is provided, to which the fuel may be introduced through a suitable fire door 17, and a door 18 is provided leading into the ash pit, this door being of any suitable form as for example that shown which is pivoted and may be used as a draft regulator. A lagging 19 of asbestos or other suitable material may be provided, as illustrated. 1

In accordance with an important possible feature of my invention, 1 provide upwardly extending fire bars 20 in the preferred form of my invention, these fire bars being of any suitable construction, as for example the plates of cast iron formed with corrugations or ribs 21.

A steam pressure gage 31 may be provided, of any suitable form, and if desired, a safety valve 32 may and preferably will be furnished, being provided if desired with a whistle 33.

Having described my invention, and illustrated the same, thus fully, I wish it understood that I do not limit myself to the specific materials and form of construction selected to enable my improvements to be understood, nor in general otherwise than as set forth in the claim read in connection the front portion thereof; a fire grate in said box; fire-bars extending upward on each side of said fire-grate; sheet. metal baffle-plates extending horizontally inward from the side walls of said fire-box toward said boiler, and from said fire-bars toward the rear' of said casing to direct the products of combustion beneath the rear portion of said boiler and around the end thereof and thereafter forward along the upper half of said boiler to said stack; said fire-box having a rear wall comprising a sheet metal member with integral upward extensions to receive and support said boiler; substantially as described.

Signed at Grimsby inthe county of Lincoln and Province of Ontario, this 2nd day of January, 1909.
